Cat Box is played with cards divided into quadrants each showing an empty box or one of five cats (in a box). Players take turns playing these cards to a shared display, overlapping previous cards by one or two quadrants. Each player is assigned a secret identity; if you are a cat you want as many of your cats showing at the end of the game as possible, and as large a group of them as possible, but if you are the chihuahua you want empty boxes and groups of exactly three cats.
